Tóm tắt

 BACKGROUND: Impact of baseline-pool local impedance (BP-LI) on the lesion size remains unclear. METHODS: Lesion size in the porcine left ventricular myocardium was evaluated using the STABLEPOINT™ catheter across various ablation settings and BP-LIs (100, 140, and 180 ohms). RESULTS: A total of 184 lesions were created with different durations (15/30/60 s) at 30 watts or with different powers (30/40/50 W) for 15 s. Lesion depth became deeper (2.8/3.0/3.6 mm at 15 s
  CONCLUSION: Lesion size decreased with lower BP-LI, and the relationship between the LI drops and lesion formation varied across the different BP-LIs. Adjusted %LI drops may serve as a more reliable parameter for predicting the lesion formation.
